General Element name- Nitrogen Element symbol- N Atomic number- 7 Atomic mass (not rounded)- 14.007
Atomic Structure Number of protons within the nucleus- 7 Number of electrons within the neutral atom- 7 Most common isotope (in the proper notation)- Nitrogen-14 Number of neutrons within the nucleus of the most common isotope- 7
Background Scientist(s) who discovered (or made) the element- Daniel Rutherford Year it was discovered (or made)- 1772 Origin of the name- From Jean-Antoine Chaptal coming from the word “Nitre” meaning producing 2 most common uses- Compounds make fertilizers and energy storers
Physical Properties State of matter at room temperature- Gas Melting point (in °C)- 210°C Boiling point (in °C)- 195.8°C Density- 1.251 g/cm cubed Abundance in earth’s crust- 0.002%
Chemical Properties Nitrogen is very difficult to react with in its purest state and one of the only elements that react with pure nitrogen is lithium Nitrogen dioxide, Nitrohydrochloricacid
Besides making up 78% of the Earth’s atmosphere, nitrogen has a ton of uses. Since it is an inert gas, it can be used to replace air and reduce of eliminate oxidation materials. The most important use is in creating ammonia, which in turn is used to make fertilizer, explosives and other materials. Finally, liquid nitrogen is used as a refrigerant for very low temperatures.
